COMBINED BOTTLE AND DRoPPINGpEvIeE.

` A.application inea `July 2.1, 19,13. serial Nol lreales.

Toallwhomit may concern." v Be it known that I, FRANK' S. I-IERETH, a citizen of the United States, residingv at the cityv of New York, in the borough of Brooklyn and State of New` York, have invented certain new and Auseful Improvements in Combined Bottlesand Dropping Devices, of which the following is a' full, clear, `and venact description. y Y Y p The invention resides in a. combined'bot tle and dropping device, particularly adapted for use `with liquids, such as medicinal compounds, chemical re-agents, andthelike. The object of the invention is to provide a bottle and a self contained dropping device therein, the two being so proportioned and arranged that the liquid may be forced in drops from the mouth of the bottle bythe internal pressure created by the dropping device. l

With this andV other objects in view, my invention consists essentially of a bottle having a contracted mouth and a rod within the bottle extending therethrough, which rod fits closely in the mouth of the bottle so that upon inward movement of the rod, a portion of the liquid will be displaced in drops if the bottle is tilted to permit the liquid therein toY fill the neck of the bottle.

In the drawings, wherein like reference characters refer to like parts, Figure 1 is an elevation partly in section of my combined bottle and dropping device; Fig. 2 is a like view showing the bottle in tilted position and the rod partially extended; and Fig. 3 is a detail showing the cap for closing the bottle when not in use.

In the construction shown, a glass bottle 1, of a suitable capacity to hold the desired amount of liquid, is provided with a relatively long and narrow neck 2.

IVithin the bottle is a solid rod 3, which is preferably of glass, although other sub-` stances maybe used, depending upon the liquid which it is desired to store in the bottle. The neck 2 of the bottle is provided with a mouth through which the liquid and rod are inserted and which may afterward be sealed as at 4 by heating the glass to melting point thus providing a hermetic closure for the bottle.

The neck 2 is scratched or scarred to form a weakened portion 5 immediate-lv below the sealed end 4. When it is desired to use the A specuita'cion of Letters-Patent.. Patented June 8, 19115,

contcntsofthe'fbottle, the Sealed ofthe neck may be broken olf at the weakened 'portion 5, to form a., mouth 6, the edges of which are relatively smooth. Theweakened portion :5 `also insuresthat f the sealed end may be readily broken oif withoutbreaking the end of the'rod, Iwhich rod isof suf,- iicient length to ,extend beyond theimoufth 6, so thatthe 'end of the by theuser. v LpQIt-ion of the liquid from the bottle. vThe rod Slis preferably made of sulficient'thickness to almostill the mouth ofthe bottle to lfacilitate the forcing of the liquid from the bottle in drops. The neck andv mouth are so proportioned that suflicientair willnot be admitted into the bottle to completelyfll the-space or vacuum left by the displacement of the air' from the 4neck of the 'bottle in case the bottle is not completely filled whenvthe bottle is tilted to permit vthe liquid to fill the neck and mouth, the pressure ofthe atmosphere against the mouth 5 of the bottle being suiicient to retain the liquid within the bottle.

When it is desired to remove a portion of the contents of the bottle, the solid rod 3 is irstrmoved outwardly which may be done before or after the bottle has been turned to the tilted position. In either case, during this outward movement, air is admitted to the bottle to fill the space or vacuum left rod may begrasped when it is desired to withdraw by the displacement of the rod. The bottle acting as a seal to prevent any more air from being admitted or exhausted from the bottle. The liquid, however, will not flow out of the bottle, as the amount of air admitted by the outward movement of the rod does not eX- actly equalize the atmospheric pressure against the liquid in the mouth of the bottle. The rod 3 is afterward acts like a piston to compress the air trapped within the bottle to slightly above atmospheric pressure. This increase of pressure is sufficient to force a portion of the liquid in the neck of the bottle out through the mouth in drops, the number of drops being controlled by the contained inward movement of the rod. It is therefore evident that I have provided a dropping device which if the same has not already to permit the liquid to run into pushed inwardly and piston-like action in conjunction with the mouthof the bottle, any desired quantity of liquid may be Withdrawn from the bottle in drops.

In Fig. 3 I have shown a cap 7 of rubber or the like, having one end closed as at 8, v

which may be used as a stopper for the bottle when the same is not in use.

Vhile I have described my invention in* connection with a specific form of bottle, it is to be understood that the invention is equallyapplicable to receptacles for liquids of all sizes and shapes, the essential feature of the invention being' that the receptaclebe so proportioned that-the liquid will remain within the bottleeXcept when it is forced therefrom in drops by an internal pressure resulting from the inward movement of the rod or dropping device. y

While I have shown a solid rod adapted to slide through the mouth of the receptacle, yet it is evident that a piece of glass tubing sealed at one or both ends would serve the same purpose as a solid rod, and the'term solid rod as used in the annexed claims is deemed suiiciently broad to cover any rod which has no passage therein through which the liquid could be forced out of theV receptacle instead of between the mouth of the receptacle and the rod.

Having thus described my invention, I claim l. A receptacle having'a closed mouth and containing a smooth solid rod fitting loosely in the mouth of the receptacle, said rod being of slightly less cross sectional area than said mouth and extending into the body of the receptacle, said rod being adapted to slide through the mouth of the receptacle for the purpose set forth.

2. The combination with a receptacle having a contracted mouth, of a solid rod with- Vin said receptacle extending through said FRANK S. HERETII.
